Adult tickets for a play cost $15 and child tickets cost $6. If there were 33 people at a performance and the theater collected $360 from ticket sales, how many children attended the play?
If you can't figure this out with an equation, try process of elimination.
14 @ 6 = 84
19 @ 15 = 285
285 + 84 = 369
Nope, the first one is not correct.
If you need an equation.
let A = # adults
and C = # children
number of attendees = 33; therefore,
A + C = 33
And cost of tickets was total of $360; therefore,
15*A + 6*C = 360
Solve the two equatins for A and C.
thank you i just didn't know how to set it up
